Both mental and physical health predicts one year mortality and readmissions in patients with implantable cardioverter defibrillators: findings from the national DenHeart study
Research output: Contribution to journal › Journal article › Research › peer-review
Background: Although highly effective in preventing arrhythmic death, there is a high prevalence of anxiety, depression and reduced quality of life among patients who have received an implantable cardioverter defibrillator (ICD). Whether mortality, ICD shock and readmission are predicted by patient-reported outcomes is unknown. Aim: The aim of this study was to describe patient-reported outcomes among patients with ICDs compared by: ICD indication and generator type (ICD or cardiac resynchronisation therapy ICD), and to determine whether patient-reported outcomes at discharge predict mortality, ICD therapy and readmission. Methods: A national cross-sectional survey at hospital discharge (n=998) with register follow-up. Patient-reported outcomes included the Hospital Anxiety and Depression Scale, Short Form-12, HeartQoL, EQ-5D and Edmonton Symptom Assessment Scale. Register data: ICD therapy, readmissions and mortality within one year following discharge. Results: Patients with primary prevention ICDs had significantly worse patient-reported outcomes at discharge than patients with secondary prevention ICDs. Likewise, patients with cardiac resynchronisation therapy ICDs had significantly worse patient-reported outcomes at discharge than patients without cardiac resynchronisation therapy. One-year mortality was predicted by patient-reported outcomes, with the highest hazard ratio (HR) being anxiety (HR 2.02; 1.06–3.86), but was not predicted by indication or cardiac resynchronisation therapy. ICD therapy and ventricular tachycardia/ventricular fibrillation were not predicted by patient-reported outcomes, indication or cardiac resynchronisation therapy. Overall, patient-reported outcomes predicted readmissions, e.g. symptoms of anxiety and depression predicted all readmissions within 3 months (HR 1.50; 1.13–1.98) and 1.47 (1.07–2.03), respectively). Conclusion: Patients with primary indication ICDs and cardiac resynchronisation therapy ICDs report worse patient-reported outcomes than patients with secondary indication and no cardiac resynchronisation therapy. Patient-reported outcomes such as mental health, quality of life and symptom burden predict one-year mortality and acute and planned hospital readmissions.
